ANTI-STICK AGENT

AVASOLS have been produced by Alframine Corporation for more than 40 years and find continued acceptance in various industrial applications as textile softening and finishing agents, dye fixatives, fiber static eliminators, emulsifiers, anti-stick agents, low-foam detergents, and yarn lubricants.

Adjustments from these suggestions are needed to accommodate equipment characteristics. In addition, in the case of tougher CSM-based compounds, a higher temperature of 60°C in the feed zone and 120°C for the die. The extmdate needs to be cooled quickly to maintain dimensions due to the thermoplastic nature of CSM. A reminder, DO NOT use zinc stearates as an anti stick agent in the cooling tank.

The tendency of sheets of rubber to stick together, dusting and anti-tack agents are used to overcome this problem. 

AVASOLS have been found effective anti-sticking and antistatic agents on resin sheetings when surface coated.

Anti-adhesive agents have been sought to prevent the sticking of the bacteria to teeth but generally these have not been successful, and bacteriocides are normally used. The problem is the mechanism of the bacterial adhesion, as shown in Fig. 12.25. It is thought that a fdm of polymer from saliva first attaches to the hydroxyapatite. Then bacteria attach to this coating. The bacteria produce a complex layer of cell sheath which glues the cells to each other. 

The uncured rubber, or stock, must fulfil several requirements to allow its successful presentation at the injection press. Most injection units are fed with strip rubber. The strip has to be of regular section and appropriate size. It should not be distorted or kinked and it should show little tendency to stick to itself. These are all features that are controlled by the choice of dump mill take-off machinery and selection of anti-tack agents. The latter should add sufficient coating to the surface of the rubber to leave the strip dry and dustless. Commercially available soap solutions have been found to be almost universally suitable for this purpose. 

Anti-blocking agents reduce the tendency of layers of film to stick together in tightly wound reels or stacked sheets. The use of an anti-blocking agent may affect the performance of other additives (such as slip or anti-static). It is therefore important that a full evaluation is carried out to determine the suitability of combinations of additives. 

Silicones confer anti-stick properties on surfaces. Moulds for rubbers, as in tyre manufacture, or for plastics are usually silicone treated to give easy release. Silicones are also useful surfactants and anti-foam agents. 

Because of their thermal stability and low viscosity-temperature coefficient, silicone fluids find use as hydraulic fluids, lubricants and greases. Other applications include textile finishes, mould release agents and anti-foaming agents where water repellency, non-stick characteristics and surface activity respectively are utilized. 

Rubbers or elastomers, like plastics, need treating with solvent to get rid of anti-stick or mould release agents, but do not soak the material as some solvents cause softening and swelling. An alternative is to wash with detergent and water which is probably the safer method. 

Slow moving slides and tables in machine tools are subject to jerky motion due to alternating slipping and sticking of the sliding surfaces. Consequently, specially developed lubricants are required to prevent and/or reduce the stick-slip phenomenon. Slideway oils usually contain polar surface-active compounds, mostly fatty acid derivatives, together with anti-wear additives and oxidation inhibitors. The polar surface-active agents form oriented boundary layers which prevent adhesive friction.
